Hi all, I have a couple of cracks up near the mast in the bilge. I don't know how long they have been there, and I was wondering if this is normal or something I should have looked at.
I have attached a couple of pictures for reference. Pic 1 is just to show the location of the other two more detailed pics.

While I am no structural engineer, or surveyor, or fiberglass expert, and I would encourage you to wait for those guys to weigh in, over time hairline cracks do develop in many areas of the hull. And that being said, I think most folks would advise checking the foot pounds tension on your keel bolts to cross out whether or not there's any Flex between the Keel and the hull. You also want to prevent any leakage of water into the layers under that spot, so you may want to put some 3500 over the cracks or even Dremel them out a bit and backfill them with epoxy or resin.
